This board is on the bench. Leave your email and you'll be first in when it ships, and your interest helps decide what we build next.
What you'll build
Time precise weld pulses for building lithium battery packs and more. You'll build the controller — precise pulse timing, high-current gate drive, a UI, and the safety interlocks that matter when serious current is involved — around an ESP32. Low-voltage control only; no mains layout.
It sits on the POWER track: power delivery, including batteries, charging, protection, and the clean rails everything else depends on.
Tools for this build
Free calculators that do the math this board needs. Each is worked from a real OTD board, with the formula and a cited source.
The build pipeline
No steps skipped, no black boxes. Each stage is gated on real proof of work: a clean ERC, valid gerbers, a passing bring-up. You finish having actually done the engineering, not just watched it.
